I tried running -mds- and received the following error message:

strings too long in name() variable

It appears that there's a bug in the code (subroutine Id2String) that sets
up the labels for the dissimilarity matrix.  When the -mds- "id" variable
contains names that exceed 32 characters, it breaks the name limit for
labeling dissimilarity matrices.  A workaround is to -decode- the "id"
variable with the "maxlength" option or, if it's a string variable, truncate
the strings.

I only tracked the error down based upon my particular use of the -mds-
command.  There may be other places in the code that are also affected, but
I'm unaware of any, since I didn't examine the code in any detail.
